UNITED STATES ALEXANDER MICHEL LOCHWITZKY, OF AUSTIN, TEXAS.

SHOE.

Application-filed February 28, 1920, Serial No. 361,965. Renewed May 8,1923.

To all whom it may concern:

Be it known that I, ALEXANDER M. LOCI-I- WITZKY, a citizen of the UnitedStates, and resident of Austin, in the county of Travis and State ofTexas, have invented a certain new and useful Shoe, of which thefollowingis a specification, the same being a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to foot coverings as boots and shoes-which Idesignate as a Siberian winter shoe, adapted to be worn by lumbermen andother persons, whose occupation requires them to perform their Work outof doors in'cold weather, and sometimes in snow and ice, especially incountries where it is very cold, as in Siberia and northern Russia, aswell as in Canada and in the northern parts of the United States.

It is well known that leather, besides being slippery on ice, conductsthe heat from the foot and admits thecold, thus making it impossible todiscover when the toes are frozen, which, after having been from eightto ten hours in that state, have frequently to,

be amputated.

I have therefore provided a foot covering that may be worn in comfort invery cold weather, as well as where there is ice, snow, or slush, andwhich comprises among other features a practically waterproof laminatedboot principally made of fabric, thelupper part of which is composed oflaminated flexible material, quilted together by cross ranges ofstitching to form superposed air chambers and having massed laminationsof fibrous material therebelow, and also a laminated and preferablyquilted sole and heeltogether with reinforcing devices and retainingmeans-whereby I obtain a foot covering which possesses the essentialproperties of great strength, flexibility and imperviousness to water,which retains the heat and keeps the foot warm while allowingevaporation and escape of perspiration, thus providing ventilation, andwhich may be worn in winter with perfect safety and entire comfort.

With the above objects and other new and useful objects and features inview, which will be described below, the invention consists in the novelconstruction, arrangement and operation of parts hereinafter set forth.

bodiment of the invention, which accompany and form a part of thisspecification,

Figure 1 represents a side elevation of an zti rticle constructedaccording to my invenion;

Figure 2 is a perspective view of the sole and heel thereof;

Figure 3 is a view in detail showing the quilting of the fibrousmaterial; I Figure 4 is a perspective view partly broken away to showthe construction of the parts;

Figure 5 is a section taken on the line 55, Figure 4t; Figure 6 is asection on the line 6-6, F i ure 1;

Figure ,7 a sectional detail view showing the structure of the sole andheel; and Figure 8 is a view in detail showing how the parts arestitched together. Referring particularl to the drawings. the numeral 1denotes t e various sheets of fabric which in laminated form comprisethe principal elements of the structure of the foot covering. Anysuitable fibrous material may be employed for this purpose whether new,or whether it has been already used for other purposes, as for example,old suitings or armyblankets, etc. or parts of them, such as are nowgiven over to army reclamation divisions, whereby a light, cheap andporous material may be provided which will be of.

low cost and long lived, besides having such adaptability to climaticchanges as will afford adequate protection from cold.

The various layers or laminations may be quilted together by threadbeing sewed through thesame in lines, as at 1", in such a manner as toprovide air chambers 10 within the cross ranges of stitches and betweenthe laminations or in the cellular structure of the fabric, as bystretching one spaced set of layers 1 tightly and by laying thealternate layers 1 loosely over the same before performing the quiltingoperation, after which the parts may be sewed together. A greater orless number of laminations may be employed according to the requirementsof use to which the boot is to be subjected.

The material is preferably made u in massed sheets which may be cut outin fines to conform to the shape of the form of the foot and ankle whenthe cut out portions are assembled. The lines of sewing or quilting ofthe stitched preferably upper portion of the shoe not only hold togetherthe layers of fabric so as to prevent wearing one on the other, but keepthem from stretching out of shape and they also serve to make channelsin the fibrous material to facilitate the escape of perspiration. 1preferably insert oil cloth or other waterproof material between thelayers of fabric to assist in preserving the -waterproof properties ofthe shoe.

The laminations at the lower part of the leg are preferably massedtogether and the parts are also preferably strengthened or reinforced byvertically disposed braces 3 at points where there is the greatest wear,which braces may enclose the meeting edges of the various pieces of theupper quilted laminations and the therebelow laminations .7 of thefabric, and are preferablyattached and also for retaining it on thewearer.

thereto by a plurality of scams 3 extending 6 to conform to the shape ofthe shoe and Y ankle of the wearer and to assist in preventing the samefrombecoming loose at the in step' and'also in holding the shoe fromslipping and preventing the same from bulging, On account of thestretching or expanding na-- ture of fibrous material, the strain of theinstep upon the boot in use would be liable to stretch or expand thefabric so as to render the same loose and floppy, thus causing thefootto work or slip in the boot which would present an unsightly appearanceand cause discomfort. I obviate these objections and preserve theappearance of the material by the use of the said strap.

1 preferably form the composite sole of the shoe by laminations orlayers of fabric 7 the edges of which are turned over at 7"and sewed toa preferably leather sole 8 preferably having an interposed layer ofoilcloth or other waterproof material 2. 1 may also use an insolecomprising a layer of leather 9 and one of fabric 9' superposed thcron,the parts holding the insole in posi tion, namely 7 and 8 being sewedtogether A supplemental sole 11 may comprise a series of laminations offabric preferably quilted together, and also a heel l2 likewisecomprising a series of laminations preferably quilted together, bothsole and heel being sewed to the interposed leather sole 8 as at S i Iwish it to be understood that I do not desire to be limited to theparticular use or the exact details of construction shown and described,for obvious modifications will occur to persons skilled in the art.

What I claim as my invention is 1. A foot covering consisting of alaminated structure comprising layers of fabric, each alternate layerbeing tightly drawn,

and the inter-mediate ones being loosely laid thereon so as to form whenquilted together by cross ranges of stitches a series of'adjacent airchambers. v

2. A foot covering consisting of a laminated structure comprising layersof fabric, each alternate layer being tightly drawn and the intermediateones being'loosely laid thereon so as to form when quilted together aseries of adjacent air chambers and a series of massed layers of fabrichaving edges, and also a strap to cover the meeting edges of the layersof quilted fabric andthe layers of massed fabric to hold them fromstrain and to draw both of the same to the foot.

3. A foot covering comprising an upper laminated structure and alaminated sole therefor comprising layers of fabric turned. in andattached to a piece of leather and having an interposed layerofwaterproof material, and also having a supplemental sole and-heelcomprising layers of fibrous material quilted together fastened to thesame.

Signed at New York city in the county of New York and State of New York,this 17th day of February A. D. 1920.
